Re: normal hearing 2

["Freed, Dan" <DFreed@xxxxxxx>]

There seems to be some controversy on this point.  See:

Martin FN & Champlin CA (2000), "Reconsidering the limits of normal hearing", J Am Acad Audiol 11:64-66.

Dear list,
In a recent posting ("normal hearing", April 2005) I found mention of the 
criteria and of the ISO standards which define normal results for 
audiometric tests.

In the summary posting it is mentioned that non-normal, by definition, is 
anything higher than 0 dB HL, and, again, that non-normal, probably in the 
field of clinical audiology, is anything below 25 dB HL (adults).

Now, my question might seem quite recursive, but:

is there a standard for deciding that the hearing of an individual is not 
standard?

Thank you,
    Bruno
